High-Quality Pool Chemicals You Can Trust

Standard Chemicals provides professional-grade pool sanitation products designed to keep swimming pools clean, safe, and crystal clear. Our calcium hypochlorite pool shock products deliver powerful chlorine performance for weekly maintenance, algae treatment, and water recovery.

Pool owners rely on chlorine sanitizers to eliminate bacteria, destroy algae, and oxidize contaminants that cause cloudy water. Calcium hypochlorite is one of the most effective and widely used chlorine treatments for pool sanitation because it provides fast-acting chlorine without adding stabilizer.

Great product in a protective bucket

Great product at a great price. Really love the bucket to keep the shock bags in so they don’t get damp in the pool shed. Will definitely order again.

Works great, cleared my pool fast

Used this to open my pool for the season. Threw 2 bags in at night and by the next day noticed a huge improvement in water clarity. Dissolves pretty quickly and seems strong compared to other shocks.

Three bags took my pool from swampy to crystal clear in no time flat.

The bags come in a quality bucket, so easy and clean to use.

Standard Chemicals hit it out of the park with this pool shock.
